Questions
How big is the Base station PCB?
It measures 86.5 × 54 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Base station use?
50 parts, built around the W25Q128JVSIQ and AP2112K-3.3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Base station KiCad files?
From the FerretCode/px1-field-analyzer repository on GitHub, at the commit this page was made from: the board is base-station/base-station.kicad_pcb and its schematic base-station/base-station.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Base station design in my own project?
Its repository states no licence, so its author keeps all rights: ask FerretCode before reusing the design.
